The following figure shows linked operation for the case when ON delay and OFF delay times have been
set for 3 UPS units.
Remote switch ON/OFF operations control UPS output as shown below.
Note that UPS operation in response to a remote switch OFF operation differs according to the Interface
setting.
Operation when Interface setting is "Standalone"
Linked ON delay time: 3 minutes
Linked OFF delay time: 10 seconds
Linked ON delay time: 10 seconds
Linked OFF delay time: 3 minutes
Linked ON delay time: 0 seconds
Linked OFF delay time: 5 minutes
User settings for linked operation
*1: Even when the linked operation ON delay time is set to 0 seconds, several seconds are required before UPS output comes
ON.
*2: You can use user setting §3.11 "UPS Operation at
supply after the UPS stops is "OFF" or "Bypass". When you select "Bypass", UPS output after the UPS stops is bypass
power supply.
However, the linked operation ON delay sequence starts at the point when UPS power supply changes from OFF to ON.
Even if you perform an ON operation in this state (bypass), the UPS does not start the linked operation ON delay
sequence. Instead, it switches from bypass power supply to inverter power supply.
If you want the UPS to use the specified "ON delay time", set §3.11 to "OFF".
Operation when Interface setting is "Workstation"
If you set the Interface to "Workstation" in §3.5 "Setting PC Interface" in the
command requesting system shutdown is sent from the UPS to the power management software when you
press the OFF button on the remote switch. The timing of the request is the OFF delay time specified in
§3.19 "Setting the Linked Operation OFF Delay Time" in the
OFF button was pressed.
The response of the UPS units to an ON operation on the remote switch is the same as when the Interface
item is set to "Standalone".
